Linear tubular switched reluctance motor for heart assistance circulatory: Analytical and finite element modeling [PDF]

, 2011
A linear tubular switched reluctance motor is presented. This actuator is devoted to be used as a left ventricular assist device (LVAD). In order to avoid thrombosis, this actuator includes pump and valve functions. By using a St. Jude Medical mechanical

Pressure, Flow Rate and Operating Speed Characteristics of a Continuous Flow Left Ventricular Assist Device During Varying Speed Support

IEEE Access, 2020
Hydraulic performance of Continuous Flow Left Ventricular Assist Devices depends on their pressure head and flow rate relations. Hydraulic characteristics of these devices are expressed by pressure head and flow rate loops in a pulsatile environment as ...

Left Ventricular Assist Devices Are Underutilized [PDF]

Circulation, 2011
Heart failure has become one of the fastest growing cardiovascular diagnoses, with estimates as high as 500 000 new cases per year.1,2 This growth is in part a result of the reductions in death from acute coronary syndromes, increased use of implantable cardioverter defibrillators, and improved survival with most cardiovascular interventions, which ...

Left ventricular assist device percutaneous deactivation with a Watchman device

, 2021
International audienceMyocardial recovery in left ventricular assist device patients is a rare event. Surgical explantation remains a risky and challenging procedure. Alternative percutaneous techniques could represent an effective solution.

Experience with percutaneous right ventricular support in the early post-left ventricular assist device implantation period (clinical case report and literature reviews)

Вестник трансплантологии и искусственных органов, 2023
Implantable left ventricular assist device (LVAD) is a state-of-the-art treatment for adults and children with end-stage heart failure. The early and late period after LVAD implantation can be severely complicated.
